About Us

A red and grey factory building with green and white glass-fibre tanks in the yard, above a fjord

Namdal Plast was founded with a clear purpose: to make fiberglass tanks that last – for fish farmers, homes and industry.

Since 1971 we've made plastic and fiberglass products in Namdalseid – today with our own product development, a large park of moulds and fitters who install across Norway and abroad.

Our Story

  1. 1971

    Founded in Namdalseid

    Production of plastic-based products starts in Namdalseid – where we still make every tank today.

    Built with fish farmers

    Solutions developed with our customers. Fish farming is our largest segment – our biggest tanks have gone to the Faroe Islands.

  3. 2018

    New owners, new course

    A new ownership group took over to modernise the company and develop new products and services.

  4. Today

    From mould to site

    Our own product development, a large mould park and fitters who install across Norway and abroad – plus daily service and repairs.

Four Values Built Into Every Tank

“Almost everything we make is produced to measure.”

  • Craft

    Almost everything we make is produced to measure – which demands real skill in drawings, mould making and casting.

  • Durability

    Glass-fibre reinforced polyester doesn't corrode. Our tanks are built to perform for decades, not seasons.

  • Local Roots

    A cornerstone business in Namdalseid since 1971 – profitable, creating local jobs and building a secure future.

  • Partnership

    Solutions developed together with our customers – and followed up with service long after delivery.

“Our people come in for a week and assemble them. We also make smaller tanks for smolt and fry farming. Because almost everything we make is manufactured to measure, it places demands on our people in terms of drawings, preparation of molds and casting. Everything from pools to tanks and the different types of grates requires expertise in these areas. Sludge separators and septic tanks are also an article, and it actually happens that we collaborate with other plastic factories on some products. It is true that others may have advantages on some projects, while we have our clear advantages on others.”
